Video feed subregion analysis tool for Arcan
This is a simple tool that was initially created for some computer vision based monitoring where the need was to specify regions in a video feed that should be tracked, then configure how these regions should be filtered and analysed.
The idea turned out to be useful for other weird stuff, some that are currently being explored is "airsynth" where each region is associated with sample playback and "robopin" looking into creating a self-playing pinball machine triggers are used to track ball location).
